Project description

Since 2008, King County Wastewater Treatment Division has been working to improve the wastewater system in southeast King County. In 2014, the County completed two new pipelines in Kent and Auburn (See Phase A info here).

We are now constructing the second phase of the project, including building 14,000 feet of new sewer line in Pacific, Algona, and Auburn, and making upgrades to the Pacific Pump Station.

Why is King County making these improvements?

To protect public health and the environment

To continue to provide safe, reliable sewer service as the area grows

To provide enough capacity to transport wastewater through 2060 in the project area

Project schedule

Construction started in spring 2017 and is expected to last for two years.
